2 Modular analyzer product line Overview Advance Optima AO2000 Series is a line of modules used for continuous process gas analysis. The product line consists of the following modules: Analyzer modules Pneumatics module Electronics module I/O modules Housing with display and control unit System bus The modules can be arranged in various ways to form single or multiple analyzer systems. The electronics module, power supply and housing with display and control unit are also collectively referred to as the central unit. Analyzer modules Analyzer modules: Uras26 Infrared analyzer module Limas11 Process photometer analyzer module Magnos206 Oxygen analyzer module Magnos27 Oxygen analyzer module ZO23 Trace oxygen analyzer module Caldos25 Thermal conductivity analyzer module Caldos27 Thermal conductivity analyzer module Fidas24 FID analyzer module MultiFID14 FID analyzer module MultiFID14 NMHC FID analyzer module LS25 Laser analyzer module Each analyzer module consists of the sensor and associated electronics having its own processor. The analyzer modules are linked to the system controller via the system bus. The laser analyzer module is linked to the central unit via Ethernet. The analyzer modules are supplied with 24-VDC from an integral power supply or an external unit. The electrochemical oxygen sensor is available as an option in combination with an analyzer module. Pneumatics module The pneumatics module contains the following elements when fully equipped: One or three solenoids to control test gas supply One or two disposable elements for fine filtration One gas supply pump with coarse filter and capillary One or two flow monitors The pneumatics module is always associated with an analyzer module and installed in the same housing as the analyzer module. Electronics module, interfaces The electronics module incorporates the system controller with the I/O modules. The system controller carries out the following functions: Processing and communicating the measured values supplied by the analyzer module sensor electronics Compensating measured values, e.g. cross sensitivity correction Controlling system functions, e.g. calibration Display and control functions Controlling associated systems, e.g. gas supply Communicating with external systems The system controller communicates with the other functional units of the gas analyzer (e.g. the analyzer modules) via the system bus. Interfaces for controlling associated systems and for communicating with external systems are located on the system controller (Ethernet 10/100/1000BASE-T interface) and on the I/O modules. The I/O modules are attached and directly connected to the system controller board. There are various types of I/O modules: 2-way analog output modules have two analog outputs. 4-way analog output modules have four analog outputs. 4-way analog input modules have four analog inputs. Digital I/O modules have four digital inputs and four digital outputs. Modbus modules have one RS485 and one RS232 interface. Profibus modules have one RS485 and one MBP interface (not intrinsically safe). Examples of I/O module applications include: Output of measured values Output of status and alarm signals Calibration control Control of external solenoid valves and pumps Measurement range switching and feedback Feed of current or status signals from external analyzers Feed of status signals from peripherals Housing The housing is available as a 19-inch (model AO2020) or wallmount (model AO2040) unit with IP20 or IP54 protection. IP54 housing versions can be purged. The display and control unit is located on the front panel of the housing when the electronics module is installed. System bus The gas analyzer s functional units are interconnected via the system bus. The system bus structure is linear with a maximum length of 350 meters. Only one electronics module with up to five I/O modules should be connected to a system bus structure. Connection of sample gas conditioning modules The SCC-F sample gas feed unit and the SCC-C sample gas cooler can be connected to the gas analyzer via the system bus by means of an I/O board installed in the sample gas feed unit. Thus it is possible to display, monitor and control individual sample gas conditioning functions in the gas analyzer such as cooler temperature or condensate and flow status. For further information please refer to the System components and accessories for sample gas conditioning data sheet. 2 Advance Optima AO2000 Series Data Sheet 10/ EN Rev. 6

Lower pressures require a sample gas pump and higher pressures require a pressure reducer. Outlet pressure Atmospheric pressure Flow rate 20 to 90 l/h Gas connections See page 9 Notes The analyzer module Limas11 HW can only be mounted in the 19-inch housing. SO 2 influences the NH 3 reading. If the sample gas mixture contains SO 2, the requirement of internal corrections must be scrutinized. When ordering the average water vapor concentration has to be specified. The influence is corrected internally. Sample conditioning system requirements Sample gas feed-in The various applications require the sample gas feed-in to the gas analyzer at temperatures of 150 to 190 C. It is imperative to eliminate condensation and sublimation since NH 3 and NO 2 are easy soluble in water and can result in salification. It is also imperative to prevent condensation of potentially present low-boiling hydrocarbons. Sample gas inlet temperature (on the process side) 150 to 190 C Sample gas filter For NO and NO 2 measurement: Sintered metal; for NH 3 measurement: Ceramics; pore width 0.5 μm Materials in contact with the sample medium PTFE, PVDF or Silicosteel Exhaust gas conditions Outlet pressure = atmospheric pressure, no resistance in the gas outlet.

Pressure correction by means of pressure sensor is recommended for single-point calibration with air. Depending on the measurement task involved, the zero- and end-points should be verified periodically (recommendation: once a year). Calibration of measurement ranges with suppressed zero-point Highly suppressed measurement ranges ( 95 to 100 vol.% O 2 ) should only be calibrated with test gases with concentrations in the selected measurement range. Single-point calibration can also be done within a suppressed measurement range. The O 2 concentration of the test gas must lie within the measurement range. 12 Advance Optima AO2000 Series Data Sheet 10/ EN Rev. 6

Otherwise a sample gas cooler or condensate trap is required. Water vapor content variations cause volume errors. Inlet pressure p e = 2 to 100 hpa Lower pressures require a sample gas pump and higher pressures require a pressure reducer. Outlet pressure Atmospheric pressure Flow rate 30 to 90 l/h Abrupt changes in gas flow rates should be avoided when using highly suppressed measurement ranges. Corrosive gases Consultation with ABB Analytical is required if the sample gas contains Cl 2, HCl, HF or other corrosive components. FFKM75 seals must be used if the sample gas contains NH 3. In this case the pneumatics module cannot be connected to the analyzer module. Flammable gases The analyzer module is suitable for measuring flammable gases and vapors under atmospheric conditions (p abs 1.1 bar, oxygen content 21 vol.%). Temperature class: T4. The sample gas must not be explosive under normal conditions. If the sample gas is explosive in the event of a sample gas supply failure, then only seldom and briefly (in accordance with zone 2). Pressure in the sample gas path in normal operation p e 100 hpa; in case of a sample gas supply failure the pressure must not exceed the maximum value p e = 500 hpa. Before using the analyzer module the corrosion resistance against the specific sample gas must be checked. Housing purge with nitrogen should be provided when measuring flammable gases and vapors. Flame barriers can be used as an option (except for the safety concept version, see page 34). Pressure drop at the flame barriers approx. 40 hpa for a sample gas flow rate of 50 l/h.

16 Trace oxygen analyzer module ZO23 Measurement principle Potentiometric measurement; zirconium dioxide cell for determination of the oxygen concentration in accordance with Nernst s equation; reference gas: ambient air. The analyzer module is used for the continuous measurement of oxygen in pure gases (N 2, CO 2, Ar). The measuring cell is catalytically inactivated to the extent that flammable carrier components in stoichiometric concentrations only negligibly reduce the oxygen value. Sample component and measurement ranges Sample component Oxygen (O 2 ) Measurement range quantity and limits 4 measurement ranges Measurement ranges are freely adjustable within the 0 to 1 ppm to 0 to 250,000 ppm O 2 range; they are factory-set to 0 to 1/10/100/1000 ppm O 2 The following measurement data refer to a measurement span of 100 ppm O 2 with a regulated flow rate of 8 ± 0.2 l/h. Stability Linearity Owing to the measurement principle, zirconium dioxide cells are base linear. Repeatability < 1 % of the measurement range or 100 ppb O 2 (whichever is greater) Zero drift The zero point (reference point) is displayed if ambient air is present on the sample gas side. The value for air of 20.6 vol.% O 2 (for 25 C and 50 % relative humidity) may deviate through aging of the cell. < 1 % of the measurement range per week or 250 ppb O 2 (whichever is greater) Sensitivity drift Depends on possible interfering components (catalyst poisons) in the sample gas and the aging of the cell. For pure gas measurements in N 2, CO 2 and Ar: < 1 % of the measurement range per week or 250 ppb O 2 (whichever is greater) Output fluctuation (2 σ) < ±0.5 % of the measured value or 50 ppb O 2 (whichever is greater) Detection limit (4 σ) < ±1 % of the measured value or 100 ppb O 2 (whichever is greater) Influence effects Flow effect 300 ppbv O 2 in the permissible range Associated gas effect Inert gases (Ar, CO 2, N 2 ) have no effect. Flammable gases (CO, H 2, CH 4 ) in stoichiometric concentrations to the oxygen content: Conversion of O 2 < 20 % of the stoichiometric conversion. If higher concentrations of flammable gases are present, higher O 2 conversions must be expected. The concentration of flammable gases in the sample gas must not exceed 100 ppm. Temperature effect The effect of the ambient temperature in the permissible range of +5 to +45 C is < 2 % of the measured value or 50 ppb O 2 per 10 C change in the ambient temperature (whichever is greater). Air pressure effect No effect through a change in air pressure; sample gas must flow out of the outlet without back pressure. Power supply effect 24 VDC ± 5 %: no effect Position effect No position effect for permanently installed instruments Dynamic response Warm-up time The operating temperature of the cell is reached after approx. 15 min. Offset calibration with reference gas (ambient air) after 2 h flow. The measurement is ready-to-run after valves and lines have been purged with sample gas. Typical purging time for valves and lines: approx. 2 to 5 h. 90% response time T 90 < 60 s for the alternation of 2 test gases in the measurement range 10 ppm with a sample gas flow rate = 8 l/h and electronic T90 time = 3 s Calibration Offset calibration The reference value for ambient air is calibrated at 20.6 vol.% O 2 by means of ambient air on the sample gas side. End-point calibration By means of test gas O 2 in N 2 (or in CO 2 or Ar); O 2 concentration in the measurement range, e.g. 10 ppm O 2 Function test An extended response time or reduced sensitivity are dimensions for the correct functioning of the measuring cell. The function test can be carried out without any additional test gases by feeding the sample gas with constant concentration. On the basis of the progression of the test, it can be assessed whether the reaction time of the sensor lies within a specified tolerance. The function test is started manually and lasts approx. 15 min. An additional function block configuration is required for a cyclic scan. 16 Advance Optima AO2000 Series Data Sheet 10/ EN Rev. 6

Sample gas inlet conditions The analyzer module must not be used for measurement of ignitable gas/air or gas/oxygen mixtures. Temperature +5 to +50 C Inlet pressure p e 70 hpa Outlet pressure Atmospheric pressure Flow rate 4 to 20 l/h. Use a metering valve to set the flow rate. Corrosive gases The presence of corrosive gases and catalyst poisons, e.g. halogens, gases containing sulfur and heavy-metal dust, leads to faster aging and/or destruction of the ZrO 2 cell. Flammable gases The analyzer is suitable for measuring flammable gases in general purpose environment. The concentration of flammable gases in the sample gas must not exceed 100 ppm. Purge gas If case purging is selected, purging may only be carried out with air (not with nitrogen), since the ambient air is used as a reference gas. 1 Sample gas inlet 3 mm Swagelok 2 Sample gas outlet 1/8 NPT internal thread 7 Purge gas inlet housing (only for IP54 version) 8 Purge gas outlet housing (only for IP54 version) Note The trace oxygen analyzer module cannot be connected to the pneumatics module. 10/ EN Rev. 6 Advance Optima AO2000 Series Data Sheet 17
